How Thermal Analysis Helped Define and Solve Major Industrial Collaborative Programs as well as the use of TMDSC in Distinguishing Between the Hydrophobic and Hydrophilic Forces

摘要

The talk will consist of two parts. In the first I will review how thermal anaysis was used across various industry-academic collborative projects in establishing an Australian national center for materials research. Interesting examples of thermal analysis in several areas of nanotechnology and polymer chemistry will be highlighted from a historical perspective. In the seconf I will forcus on a particular academic research prgram and how thermal analysis was used to distiguish between the hydrophobic and hydrophilic forces resident in self assembling amphiphilic molecules. Here five amphiphilic lipids were self-assembled in aqueous dispersions into high axial ratio nanostructures. The morphologies of these aggregates included high axial ratio nanostructures, such as nanotubes; and flat, twisted, and helical ribbons, which reveal complex and intriguing thermal behavior by DSC.Thermal analysis was conducted on these glycolipids that self-assembled into nanotubes,showing a dry melting onset of 148.2 ℃ to be defined as well as evidence of a highly ordered supramolecular structure. The use of TMDSC in resolving hydrophobic versus hydrophilic associations in these structures will be discussed.
